Missed shift and over revved on my SI.

[Schmullis]

The car has a rev limiter. As long as that is functioning, you should be fine. If not and it's not due to you changing the ECU, that should be covered under warranty. Either way, just bring the car in for a check up at the dealer and don't tell them you over revved, just tell them it's performing strangely.

The Civic would record the over rev and nope that wouldn’t be warranty. That would be 100% on the nut between the wheel and the seat.....

Wait! What? No rev limiter on the SI?!

No rev limiter on a missed down shift. It only protects you if you wind a gear out on the way up!

No rev limiter will stop the road surface, quickly passing by under the car, from overrevving the engine via the wheels, the differential and the gearbox which is set to a too low gear.

The rev limiter can only stop the engine from overreving itself as a result of too much throttle ordered by the driver.

But in this case it seems like there was no overrevving, only revving much higher than the driver intended. It's important to be always ready to abort a mis-shift by quickly stepping on the clutch (before even trying to jerk back the stick). The rev spike that may result is not a big deal.

There is at least one of these threads on every car forum. In every case, the OP is in a panic and there is never damage to the car, only the pride of the driver.

You're fine. You just missed a shift. It happens. You survived and so did your car. If you did damage you'd know about it by now.
As stated, there in no protection from over revving your motor when you miss a shift. Even so, you're still fine.
